Abstract: To analyze a gait of a person accurately regardless of a photographing direction of a camera.SOLUTION: A gait analysis device adjusts a size of a human region included in a frame so as to cancel the variation in the size of a person shown in the frame for each frame included in a moving image capturing a gait of the person. Next, a GEI (gait energy image) is created by overlapping the size-adjusted human regions. Next, a differential image of GEI and the contour of the size-adjusted human region are matched, and the amount of movement of each human region with respect to the differential image is calculated. Further, the movement amount is corrected, and the characteristic amount of the gait of the person is calculated based on the corrected movement amount. The amount of movement is corrected by deriving an approximate function of the amount of movement by fitting the calculated amount of movement to a logarithmic function of a size of the person reflected in the frame, and subtracting the value of the approximate function from the calculated amount of movement.SELECTED DRAWING: Figure 4
